Frank, I am surprised that there is still so much mis-understanding about the Cdn Parachute Corps badges around. Ken Joyce's
Into the Maelstrom Service Publications, now the standard reference has been available since 2007. (Lou Grimshaw's booklet was a good start but Lou did not have access to the archive material that Ken Joyce accessed in both the UK and Canada.) The evolution of both the other ranks and officers badges are detailed, including the historical context, authorizations, production and distribution issues. Additionally images of archive documents and actual badges illustrate this chapter. If one collects Canadian airborne insignia, this is the key reference.
